Here's the vicinity of that line, including what I hope is the necessary 
context:
------------
fmtutil [INFO]: log file copied to: 
/usr/local/texlive/2023/texmf-var/web2c/pdftex/jadetex.log
fmtutil [INFO]:

So it looks like this "unitialized value $_[4]" happened twice.

I did a little looking around for libfontconfig.so.1, which seems to 
have triggered the unitialized the second time, and confirmed that I 
can't find it either.  But then it's always been a bit of a mystery to 
me as to how to find libraries.  I suppose if I install that, I could 
fix at least one of the error msgs, but the problem appears to be 
deeper--it appears to be with the error logging (and maybe the script 
should check for this library file before it starts running stuff?).
